Title: Device for removal of gas from a liquid in any orientation
Inventor: VERKAART WESLEY H
IPC: A61M5/38
Filed: 1993-01-04
Abstract: ABSTRACT A device for reducing the amount of a gas contained in a liquid includes a central core with an inlet channel, an outlet channel, and a transverse channel.   A first chamber is formed on a first side of the core for receiving the liquid from the inlet channel, and a second chamber is formed on the opposite side of the core for receiving the liquid after it has passed through the first chamber.  Each of the chambers includes a hydrophobic membrane for allowing gas that has separated from the liquid to pass to the atmosphere.  The two chambers are arranged such that gas escaping from the liquid rises to the top of at least one of the chambers for any orientation of the device. The device, accordingly, is not dependent on orientation for effectiveness.

Title: Hydraulic drive system
Inventor: VACHON BERTRAND
IPC: B60K25/02
Filed: 1993-01-27
Abstract: ABSTRACT      A combined hydraulic circuit to be used with an hydraulically powered implement of a motorized equipment and its engine-driven host vehicle. The combined hydraulic circuit  permits  the  implement to be  operated with a vehicle,  such as a tractor,  which does not have the adequate capacity to power the implement without the usual requirement of using an hydraulic fluid reservoir and a filter  in  the  independent  hydraulic  circuit  of  the implement.  Instead,  the  implement  uses  the  tractor hydraulic circuit to clean, cool and pressurize in part the hydraulic fluid in its hydraulic circuit which has an hydraulic motor or an hydraulic cylinder driven by an hydraulic pump. This hydraulic pump could be a gerotor pump since the supplied fluid entering the pump is already pressurized unlike a circuit that uses an hydraulic fluid reservoir. The implements may be rotary brooms, mowers, portable  saw  mills,   hoeing  machines,   loaders  or snowblowers.

IPC: E05B65/464
Filed: 1993-06-23
Abstract: An interlock mechanism for a multi-drawer file cabinet assembly, for preventing more than one drawer from being opened at a time.  The interlock mechanism includes a series of control rods mounted for axial movement within a series of blocks located in the interi-or of the cabinet.  The control rods are arranged in an abutting end-to-end relationship, forming joints therebe-tween.  A pivotable lever is mounted to the blocks adja-cent each joint, and an actuator member is mounted to each drawer.  Movement of a drawer to its open position causes engagement of the actuator member with one of the levers, to pivot it to a position in which the lever separates adjacent control rods, resulting in upward or downward movement of the control rods and vertical dis-placement of the joints between adjacent control rods. The remaining levers engage the control rods at a loca-tion spaced from a joint between control rods, to prevent the remaining drawers from being opened.  Movement of the drawer back to its closed position causes engagement of the actuator member with the pivotable lever, to pivot the lever to its inoperative position out of engagement with the control rods.  The control rods are returned to their original abutting position under the force of springs.

Title: Method and apparatus for assessing and restoring solderability
Inventor: TENCH D MORGAN
IPC: B23K1/20
Filed: 1993-09-03
Abstract: A sequential electrochemical reduction method and apparatus are provided for assessing and restoring solderability of electronic component leads. The method detects and quantifies the presence of metallic oxides that are detrimental to solderability by sequential electrochemical reduction in contact with an electrolyte in an inert atmosphere. A cathode having a high hydrogen overvoltage is placed in contact with the electrolyte. A solderable portion of the component to be tested is placed in contact with the cathode and the electrolyte. An inert counter electrode and a reference electrode are also placed in contact with the electrolyte. A current is passed between the cathode and inert electrode, and the voltage and current are measured as a function of time during reduction of metallic oxides on the solderable portions of the component. The measurements of voltage, current, time, and charge density may be compared with baseline data from specimens having known oxide compositions that correlate with degradation of solderability.

Title: High water content hair spray composition
Inventor: LOGIN ROBERT B
IPC: A61K8/49
Filed: 1992-07-06
Abstract: What is described herein is a high water content hair spray composition which forms uniform, fine spray patterns having rapid drying characteristics, and which provides excellent curl retention, and reduced curl droop properties. These results are achieved herein by incorporation a surface active agent or agents into the hair spray composition which agent or agents substantially decreases the surface or interfacial tension of the hydroalcoholic phase of the composition during use. The decreased surface tension of the water-based composition along the length of the hair shaft enhances its spreading tendencies so that substantially no droplets can form upon application of the composition to the hair. The surface active agent preferably is a surface active lactam; and, most preferably, an N-alkyl pyrrolidone, where the alkyl group is a C4-C22, branched or linear, alkyl group.
Patent CA-2115388-A1 (CA)
Inventor: BREED BEN R
IPC: G01B7/004
Filed: 1994-02-10
Abstract: Dipole detection and localization systems and methods employing improved processing techniques.  The first processing technique provides for higher spatial resolution by implementing maximum likelihood beamforming processing to detect and locate a dipole in a manner analogous to the processing of wave propagation phenomena. The high resolution technique is comprised of using data derived from an array of magnetic sensors that is arranged in the form of a vector of coefficients in lieu of a matrix.  This vector can be either the magnetic field components or the Andersonfunction expansion coefficients and is used to form a dyadic matrix, to which a multiple of an identity matrix is added to prevent singularity.  The second improvement uses more than three Anderson function expansions to achieve detection and localization of the dipole.  The use of more than three Anderson functions more effectively normalizes out the noise dependence by providing better noise representations, and provides fordetection and localization of multipoles. The third improvement provides for multiple-pass multiple-target processing of data measured by the array of sensors. First, the location of the largest dipole in the field-space of the array is determined, and its moment and orientation are determined. The field due to a dipole at that location and orientation is then removed from the measurement data and the process is repeated. The field isremoved by subtracting out its contribution at each of the sensors in the array, and then estimating the location of the next largest dipole. Simulations have shown that this process provides the ability to resolve multiple dipoles, when applied as many times as is needed.  Among other fields of use, the present invention has application in non-acoustic anti-submarine warfare applications.

Title: Hydraulic jack pump
Inventor: DINGWALL TERRY
IPC: F04B47/12
Filed: 1994-02-28
Abstract: An oil pumping jack of improved efficiency and safety, with an electric-hydraulic manifold that provides soft shift spool in normal operation. Hydraulic compensation in the form of sacrifice of fluid output is provided if the work load increases, so that the system slows down visibly, signalling the operator and avoiding downhole damage. Further efficiency is achieved through avoidance of horizontal forces on the well-head linkage by fashioning the horseheads to have the face farthest from the center of rotation of the fulcrum beam be a convex portion of a circle circumference whose radius is the distance to the center of rotation. Safety features include a safe and total shutdown by interruption of the electrical control circuit, a positive hydraulic lock holding the pump jack in its stopped position without pressure on the hydraulic seals or fittings, and a longer circumference on the balance horsehead to facilitate tapping the well-head bottom without manual adjustments.
